In addition to scale warm-ups, we also build chords and try to play the different chords of a given key. With the notation system generator noteflight, I can now create my own chord progressions for the group to use an play. Each instrument and be assigned a specific note of the chord to play. Not only can noteflight generate a score which you can see below, but it will also generate individual instrument parts so that the students can have their own part to play from. A great tool that is useful and much more meaningful for instruction than purchasing a method book that often has material that is either not useful or redundant.
